My boyfriend is only 35 and he had a stroke recently. We think it's because he was a heavy smoker, so he's just quit smoking and drinking cold turkey. Since then, he has not been sexual at all, this is not like him at all. He is tired a lot which is understandable, but i am wondering if any of these things could have caused him to lose his sex drive? People say their sex drive is increased after quitting smoking, so could it be the stroke? Will it get better?
